John Adams Crystal Radio Kit Ferrite Coil Wiring
The photograph on the box shows the ferrite bar installation upside-down, and all the antenna coil wires fed through a single hole. Do not follow that, as it is wrong. Instead, follow the diagram on page 4 of the manual, or this page.
Connections
- Black wire to Terminal 2
- Yellow Wire to Terminal 5

Ferrite Rod and Coil
Antenna Coil Colouring
Wire Routing
The green and yellow wires from the antenna coil feed through the RHS hole, whilst the black and white wires feed through the LHS hole as shown in the photograph. The remaining hole is for securing the ferrite bar using a nut and bolt. Slide the coil to the far edge of the ferrite rod so that only 5 mm of the rod is showing from that end.
Securing the Rod
After routing the ferrite coil wires through the relevant holes, use the remaining hole for securing the ferrite bar using the supplied nut and bolt.
